This was one of the first licensed Simpson's games, and until Virtual Springfield came out years later for Windows 95, the best one. The controls could be horribly annoying until you get used to them, but the game offers such a wide range of things to do that it's difficult to get bored. The graphics are true to the show, the main theme is intact and well-rendered by NES standards, and the voice clips really give the game an added punch.
Great game, well worth the time, and nowhere near as hard as people like to make it out to be. Well, to be fair, I got this for my birthday a couple months after it came out and played it to death, and still regularly go back to it. That probably helps the difficulty level :)
